Apple TV and iOS are prone to a heap-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer. An attacker can leverage this issue to execute arbitrary code with system privileges. Failed exploit attempts will likely result in denial-of-service conditions. NOTE: This issue was previously discussed in BID 69882 (Apple iOS Prior to iOS 8 and TV Prior to TV 7 Multiple Vulnerabilities) but has been given its own record to better document it.
